Electricity-Free rotary wind blowing apparatus

Abstract

An electricity-free rotary wind blowing apparatus including a wind guiding device, a spreading device and a supporting device. The supporting device has a central seat portion disposed with an inner bearing. The spreading device is rotatable secured to the bearing. The wind guiding device has a central shaft seat and a peripheral rim. Multiple radial inclined wind guiding vanes are disposed between the shaft seat and the peripheral rim. The air flow blows from the wind exit of a wind pipe of an air-conditioning system onto the vanes and is guided thereby so as to exert a rotating force onto the spreading device, whereby the spreading device itself is rotatably driven by the air flow without using electricity to evenly spread the air flow.

What is claimed is: 
     
       1. An electricity-free rotary wind blowing apparatus comprising: a wind guiding device having a central shaft seat and a peripheral rim, multiple radial inclined wind guiding vanes being disposed between the shaft seat and the peripheral rim;   a spreading device having multiple inner concentrical annular inclined spreading plates and between each two spreading plates are disposed spaced supporting ribs for securing the spreading plates, the spreading device having a central shaft seat fixedly secured to the shaft seat of the wind guiding device by a fastening member to synchronously rotate therewith; and   a supporting device which is a wheel-like body having a central seat portion rotatably connected with the fastening member between the wind guiding device and the spreading device, whereby the wind guiding device and the spreading device can be supported by and rotated about the seat portion, the seat portion being disposed with a retaining member, the edges of the supporting device being connected with a periphery of the wind exit of an air-conditioning system.   
     
     
       2. A wind blowing apparatus as claimed in claim 1, wherein the supporting device is located between the wind guiding device and the spreading device. 
     
     
       3. A wind blowing apparatus as claimed in claim 1, wherein the wind guiding device is a flat wheel-like body. 
     
     
       4. An electricity-free rotary wind blowing apparatus comprising a wind guiding device, a spreading device and a supporting device, wherein the supporting device has a central seat portion disposed with an inner retaining member, the spreading device being disposed with multiple inner concentrical annular spreading guiding plates and the wind guiding device being disposed with multiple inner radial inclined vanes, the spreading device and the wind guiding device being rotatably connected with the retaining member by a shaft to synchronously rotate. 
     
     
       5. A wind blowing apparatus as claimed in claim 4 wherein the wind guiding device is located between the spreading and the supporting device. 
     
     
       6. A wind blowing apparatus as claimed in claim 4, wherein the spreading device is located between the wind guiding device and the supporting device. 
     
     
       7. A wind blowing apparatus as claimed in claim 4, wherein the spreading device is located under the wind guiding device. 
     
     
       8. A wind blowing apparatus as claimed in claim 4, wherein the wind guiding device is located under the spreading device. 
     
     
       9. A wind blowing apparatus as claimed in claim 4, wherein the wind guiding device is directly disposed in the spreading device as radial vanes integrally connected with the spreading guiding plates thereof. 
     
     
       10. A wind blowing apparatus as claimed in claim 4, wherein the spreading guiding plates of the spreading device are connected with each other by multiple supporting ribs disposed therebetween. 
     
     
       11. A wind blowing apparatus as claimed in claim 5, wherein the spreading guiding Plates of the spreading device are connected with each other by multiple supporting ribs disposed therebetween. 
     
     
       12. A wind blowing apparatus as claimed in claim 6, wherein the spreading guiding plates of the spreading device are connected with each other by multiple supporting ribs disposed therebetween. 
     
     
       13. A wind blowing apparatus as claimed in claim 7, wherein the spreading guiding plates of the spreading device are connected with each other by multiple supporting ribs disposed therebetween. 
     
     
       14. A wind blowing apparatus as claimed in claim 8, wherein the spreading guiding plates of the spreading device are connected with each other by multiple supporting ribs disposed therebetween.
